I have Debian host that runs my Meteor application on NodeJS that listens: 127.0.0.1:3999 I also have a domain register https://example.com that welcomed with Apache and proxied to my Meteor application.
I have problem with DDP Connection.
my connection link is ws://example.com/websocket
I set the ProxyPass settings as following:
<VirtualHost *:443>
ServerName example.com
ServerAlias www.example.com
SSLEngine on
SSLProxyEngine On
ProxyRequests Off
SSLCertificateFile /etc/apache2/ssl/www.example.crt
SSLCertificateKeyFile /etc/apache2/ssl/www.example.key
SSLCertificateChainFile /etc/apache2/ssl/sub.class1.server.ca.pem
ProxyPass /websocket ws://localhost:3999/websocket
ProxyPassReverse /websocket ws://localhost:3999/websocket
ProxyPassMatch ^/sockjs/(.*)/websocket ws://localhost:3999/sockjs/$1/websocket
ProxyPass / http://localhost:3999/
ProxyPassReverse / http://localhost:3999/
BrowserMatch "MSIE [2-6]" \
nokeepalive ssl-unclean-shutdown \
downgrade-1.0 force-response-1.0
# MSIE 7 and newer should be able to use keepalive
BrowserMatch "MSIE [17-9]" ssl-unclean-shutdown
</VirtualHost>
And
<VirtualHost *:80>
ServerName example.com
ServerAlias www.example.com
ProxyRequests off
RewriteEngine on
ReWriteCond %{SERVER_PORT} !^443$
# This allows DDP clients like ObjectiveDDP and Meteor-Unity to connect
RewriteRule ^/websocket wss://%{HTTP_HOST}/websocket [NC,R,L]
# This allows the meteor webapp to connect
RewriteRule ^/sockjs/(.*)/websocket wss://%{HTTP_HOST}/sockjs/$1/websocket [NC,R,L]
RewriteRule ^/(.*) https://%{HTTP_HOST}/$1 [NC,R,L]
